Cascade Pole Olympia

Shoreline near Cascade Pole

Cascade Pole, Olympia is located at 1100 Washington Street NE, at the north end of the Port of Olympia peninsula between the east and west bays of Budd Inlet. From 1957 to 1986, the Cascade Pole Company operated a wood-treating facility on property leased from the Port of Olympia. Before then, several other wood-treating businesses operated at the site. The site is contaminated with polynuclear aromatic hydrocarbons (PAH's -- key chemical constituents of creosote, a wood-preserving compound), pentachlorophenol (PCP, another wood-preserving compound), volatile hydrocarbons, and dioxins in soils, groundwater, surface water, intertidal (the section which is covered at high tide and uncovered at low tide) sediments, and marine organisms on and adjacent to the site.
